Thank you for sharing your opinion with us. I do agree that demos can be a valuable resource, yet in the same time they need to be simple enough for other people to start examining the controls.
This is why we are starting work on an SDK for the RadContorls for ASP.NET AJAX
that will start hosting various examples as well to help developers. If you have ideas, suggestions or samples you would like to see available there - do let us know. It is still in development and having our customers' feedback can help us make it more valuable for all.
